Description

Passivhaus consultancy and M & E engineering design for a single-family off-grid home, certified Passivhaus Premium and BREEAM, and built with renewable bio-based materials, including a lightweight timber frame structure and wood fibre insulation.

Passivhaus consultancy included PHPP energy simulation and performance optimisation, thermal envelope design, strategies to combat summer overheating and thermal bridge calculations.

HVAC design included an air-source heat pump for heating, cooling and DHW production, ducted mechanical ventilation with heat recovery, and a dehumidifier/cooling and heating cool with radiant ceiling panels. All services were integrated and controlled with the Loxone home automation system, providing extensive monitoring and preventative maintenance capability. An on-site solar photovoltaic installation and battery system means the home is entirely energy self-sufficient, with no grid connection. The home also has a rainwater collection and grey water treatment system, with no mains water connection.
